A much sought-after species. Known only from a single site in County Clare, P. mammilosa is a soil-inhabiting Porina. The rather thick, uneven thallus produces perithecial discs (0.3–0.5mm diam.) with pink, orange and yellow internal pigments, which burst through the surface taking a layer of grey thallus with them. Spores are three-septate, narrower than in P. sudetica.
